I Have No Idea What Goes On In My Head

I was driving along the other day, thinking about what a reverse Reece’s peanut butter cup* would look like, when another thought struck me. If someone donates an organ, like a kidney or a part of their liver, to somebody and that person is an organ donor, when they die does the donated organ go back to the original owner or does it get passed on to someone new? Is there like a tiered system where the original owner gets like an option to have the organ back, and would anyone really want an organ that has been inside another person stuck back in their body?

These are the things I think about while I’m sitting at traffic lights.
